Thermal effects on materialsUPM
Refractory metals (W Ta Mo Nb Zr) are very expensive but ceramic-metal composites are in use. Ordinary metals like steels and aluminium cannot resist high temperatures. Aluminium alloys should not be used above 500 K due to loss of strength (but titanium alloys may be used up to 900 K).

SuperalloyWikipedia
A superalloy or high-performance alloy is an alloy with the ability to operate at a high fraction of its melting point. Several key characteristics of a superalloy are excellent mechanical strength resistance to thermal creep deformation good surface stability and resistance to corrosion or oxidation.. The crystal structure is typically face-centered cubic (FCC) austenitic.

High-purity Refractory Metals for Thin Film Metallization
Nov 11 2016 · During high-temperature vacuum melting or annealing of refractory metals dissolved atoms of gas-forming and metallic impurities diffuse to the metal surface and desorb from it. It means that there are optimal conditions for vacuum evaporation of metal impurities because their vapor pressure becomes very high at T m of refractory metals.
